The invention provides a traffic road participant collision early warning method and apparatus, and an electronic device. The method comprises the steps of obtaining cooperative sensing information CAM corresponding to a current vehicle and a moving target in a preset range of the current vehicle, wherein the CAM comprises current vehicle information, moving target information, first time and second time; searching current vehicle information corresponding to first time less than a first threshold value and at least one piece of moving target information corresponding to second time less than the first threshold value, and storing the current vehicle information and the at least one piece of moving target information; aiming at the stored current vehicle information and each piece of moving target information, calculating collision parameters corresponding to the current vehicle and the moving target by utilizing a collision detection algorithm, carrying out priority ranking on multiple groups of collision parameters obtained by calculation according to a collision time threshold and a collision space threshold, and sending an alarm message according to a priority sequence. Therefore, the cost can be saved, the detection performance is improved, the detection range is widened, the generalization performance is higher, the early warning effect is good, and the safety requirement is met.

    本申请提供一种交通道路参与者碰撞预警方法、装置及电子设备,该方法包括:获取当前车辆与当前车辆预设范围内运动目标对应的协作感知信息CAM;该CAM包括当前车辆信息、运动目标信息、第一时间和第二时间;查找小于第一阈值的第一时间对应的当前车辆信息和小于第一阈值的第二时间的对应的至少一个运动目标信息,并进行存储;针对存储的当前车辆信息和每一运动目标信息,利用碰撞检测算法计算当前车辆和运动目标对应的碰撞参数,根据碰撞时间阈值和碰撞空间阈值将计算得到的多组碰撞参数进行优先级排序,并按照优先级的顺序发送警报消息。这样,可以节省成本,提高检测性能及检测范围,推广性较高,预警效果好,满足安全所需。
